AI Technical Summary

Technical Problem

In existing CO2 gas shielded welding, the orifice of the contact tip wears and enlarges during use, resulting in weakened conductivity of the welding wire, short service life, low utilization rate of precious non-ferrous metals, and large scrap volume, causing resource waste.

Method used

A conductive tip processing device and method are adopted, which controls the wire tension by electro-hydraulic oil jack, measures the friction force and deforms the conductive tip orifice diameter, changing it from a straight line to a curve, restoring the conductivity and preventing the welding wire from rotating inside the conductive tip.

Benefits of technology

Extend the service life of the contact tip, improve the utilization rate of precious metals, reduce procurement costs, and ensure the stability and precision of the welding process.

Abstract

This invention discloses a conductive tip processing device and method. It precisely processes used conductive tips that have reached the end of their service life, causing them to deform and changing the original straight aperture to a curved aperture. This increases the contact area and friction between the welding wire and the inner wall of the conductive tip, restricts the oscillation amplitude of the welding wire passing through, restores the conductive tip's conductivity stability and basic function of limiting and constraining the welding wire end, thus meeting the requirements of the welding process. The purpose of this invention is to enable the reuse of used conductive tips, effectively extend their service life, improve the utilization rate of precious non-ferrous metals, and reduce the waste of scarce resources.
